Abstract
Semiconductor Zinc Oxide (ZnO) nanoparticles have been successfully synthesized by hydrothermal method by varying the growth times. The effect of growth times was investigated by means of X-ray diffraction (XRD), Increasing the time of growth has successfully increased the crystalline of the ZnO nanoparticles. The average particle size have been found to be about 50-70 nm. The absorption edge of the samples has showed and the band gap energy has been calculated.
